Just FYI assuming you stick with the Neon:
Using available Neon aftermarket parts will attract certain demographics at an enthusiast gathering that will either react in a "LOLZ coolz wutz dat?" or a "yeah, but how quick is it through the cones?" Assuming you want to demonstrate electric drive's potential (pun only slightly intended) to supplant fuel burning in the here and now you should Autocross it (SCCA Solo II) as Neons do pretty well in that forum. When a Neon is driven hard through corners they will lift the inside rear tire completely off the ground to achieve the proper cornering response as three-wheel cornering dynamics differ greatly from four-wheel dynamics. I doubt that this characteristic would be complemented by RWD.
Keep the FWD and even the transmission. Figure out which gear/final drive combination suits Auto-X speeds (usually up to 35/40 mph) to maximize your motor's effectiveness without shifting. Keep your center of gravity low and weight bias slightly forward (about equal to stock) to keep the oversteer-inducing wheel lift (they really do apex a corner faster that way).
